Multiple Hop SSH to SFTP

See more SFTP Examples

Demonstrates how to SFTP through an intermediate SSH server (multiple hop). The scheme looks like this:

Application => ServerSSH1 => ServerSFtp

The ConnectThroughSsh method is added in Chilkat version 9.5.0.55 to accomplish this task.

Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

let ssh1 = chilkat::Ssh::new();

// Hostname may be an IP address or domain name:
let hostname = "192.168.1.111".to_string();
let port = 22;

// Connect directly to the 1st SSH server:
if ssh1.connect(&hostname, port).is_err() {
    println!("{}", ssh1.last_error_text());
    return;
}

// Authenticate using login/password:
if ssh1.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", ssh1.last_error_text());
    return;
}

// Connect through the 1st SSH connection to reach a 2nd SSH server (for SFTP)
// Note: Any number of connections may be simultaneously tunneled through a single
// existing SSH connection.
let sftp = chilkat::SFtp::new();

// Connect to some SSH/SFTP server through ssh1.
if sftp.connect_through_ssh(&ssh1, "sftp.someremoteserver.com", 22).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Authenticate with the SFTP server. 
if sftp.authenticate_pw("myLogin", "myPassword").is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// After authenticating, the SFTP subsystem must be initialized:
if sftp.initialize_sftp().is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

// Upload from the local file to the SSH server.
// Important -- the remote filepath is the 1st argument,
// the local filepath is the 2nd argument;
let remote_file_path = "hamlet.xml".to_string();
let local_file_path = "c:/temp/hamlet.xml".to_string();

if sftp.upload_file_by_name(&remote_file_path, &local_file_path).is_err() {
    println!("{}", sftp.last_error_text());
    return;
}

println!("Success.");

// Close the connection with the SFTP server.(This closes the the tunnel through ssh1.)
// The connection with ssh1 is still alive, and may be used for more connections.
sftp.disconnect();

// ...
// ...
// ...

ssh1.disconnect();
